A tube |68 of resilient material, such as rubber, iills the hollow portion of eachpipe or hollow rod |65 and a knock-out pin |69 extends into each tube |68; provided with a pivot or fulcrum ring |10 near one end of the tube |68. The tube |68 fits tightly around the ring |10. Each pin |69 islalso provided with a ring |1| slightly less in diameter Vthan'tlre hole in the rod or pipe |65 and'with a ring |12 e while the pockets 2 of the strip are immediately slightly larger than this hole with its opposite sides flattened, as shown at |13. The'flattened sides |13 of the pin |69 fit closely into the notched end |14 of the rod |65, the sides of this notch being parallel to each other. lEach pin |69 terminates in a circular head or ring |80. Each hol-v low rod or pipe |65 has a sleeve |82 keyed thereon,

(Fig. 4), as shown at |83, and these sleeves are j provided with toothed anges |84'. The opposite sides of the sleeves |82'vare flattened, as shown` teeth of the flanges |84.

A spider |90 (Figs. l andl) has a frictional connection, as shownat |9|, with the hub |92 of the feeding wheel |30. The spider |90 can be held stationary while the jhub V'|92 is revolving or the spider |90 will revolve with the hub. |92 by the frictional engagement therewith, unless it is held by a stop or the'like to prevent it from revolving. The spider v|90 carries a toothed vsegment`,|93 with half las many teeth as the number on the flange |84 of the sleeve |82. 'Ihe segment |93Y is located in the path of the planetary `travel of the The spider' |90 also carries a ring |94 concentric with, the shaft |35 and located sothat the flatsides |85 of the sleeves |82 rub against theinner surface |95 ofthe ring |94 as they are carried around bythe revolving 'wheel |30. A notch or cut-out portion |96 .(Fig.

'1) is provided along the inner surface' of the ring 1 |94 in proximity to the toothed segment |93. Y

As thewheel |30 is revolved tobring the metal blocks |56 intorthe lowerportion of their path, the material to be fed into the pockets'Z of the strip is pressed by the packing wheel |44 through the openings |6| in the. metal blocks and into thevupper charging pockets |61 of the charge measuring dispensing rods or pipes |65 that areY revolubly mounted in the transverse holes or bearings |62 ofthe metal blocks |56. The sliding of the flat sides of the sleeves |82, that are on the rods or pipes |65, along the inner edge |95 of the ring |94 keeps the pockets |61 turned toward theV center of the wheel |30 so as to receive vthe material. When the sleeves |82 reach the cutout portion |96, they are free to revolve. At this moment, the teeth |84 strike the stationary teeth |93 and since there are half as many lteeth Y|93 as there are teeth |84, each sleeve |82 will be -turned one-half of a revolution at the cut-out'V portion |96, thus bringing the pockets |61 thereof opposite the openings |63 in the metal blocks |56.

. At the same time, the strip is carried along the outside lor lower surfaces of the blocks |56 at the peripheral speedrof these blocks with theA pockets 2 ofthe strip r| immediatelybelowthe openings |63 so as to receive the material therefrom. As

. soonas a sleeve |82 is'turnedfonehalf a revolution by the toothed segment |93, the other 'fiat surface Each knock-out` pin |69 is T 85 thereof is caused to slide along the inside surface |95 of the ring |94 so that the other pocket |61 of the corresponding pipe |65 is brought into position to be charged with material the next time the pipe |65 is brought around to the charging position, `thus vcausing alternate pockets |61 in the pipe |65 to bel charged anddischarged at successive revolutions of the wheel |30.

f The material, especially if in powdered form, would sometimes become clogged in the pockets A|61 and not drop into the pockets 2 when the pipe |65 is turned, and for this reason, the knock-out pin |69 is used." The spider |99 carries a roller |91 located in the path of the heads |80 of the knock-out `pins |69, so that the heads |80 will strike the-roller |91 Yimmediately after the pipes |65'have'been:v revolved half a revolution, and

below the, openings |63 of the metal blocks |56. WhenV the head |80 strikes the roller |91, the fiat sides |13 of the ring portion |12 of the knockoutfpin|69 is moved upwardly along the notched end- |14 ofthe pipe |65 and since this pin is fulcrumed at |10, Vits opposite end extending into therresilient tube |68 between the pockets |61 Will give a blew `to the material in the lower pocket |61 through the'resilie'nt material, thus loosening the material if it should happen to be caught and causing' it toVV drop into the corresponding pocket 2. When it isdesiredto permit the wheel |30 to revolve without feeding charges of material into thepockets v2, the stationary stop or obstruction that prevents the spider from revolving is removed, so tliatthe pipes |65 are not reversed anywhere in their annular path of travel and therefore -no materialisfed from the wheel |30 under these conditions.
